I'm conducting an experiment dealing with differences in padding across different aes operations for my Intro to Crypto class, and the question says OpenSSL uses PKCS5 padding, and that I need to prove this. All we've been taught up to this point was how to encrypt something by doing this:
openssl enc -aes-128-cbc -e -in example.txt -out example.bin -K 1001001 -iv 0100110
Now my question, really, is: Where do you implement the padding into this shell command, or is the padding automatically added, and if it is auto added, why can I not see in it my hex editor?
